Connect to BOX storage

Hi,

I am trying to connect to BOX storage from Power BI desktop through WEB source. If the file download permission is enabled then I am able to fetch the data directly through web source but if the file is protected with password or download permission is not enabled then it is not possible to fetch the data directly. Could any one please suggest what is the effective way to connect BOX storage from power BI.

Regards
